To avoid refund delays, select your refund preference using the Macomb OneCard mailed to you in the green envelope approximately 2 weeks after your first registration. If you have not received it, contact the Macomb OneCard office. Payments made with a credit/debit card are refunded first. Other refunds are based on the refund preference selected - Electronic Deposit to Another Account or Electronic Deposit to a BankMobile Vibe Account.
